Thread: Anyone know a good 2D plotting program?

There's a 2d and 3d plotter online.

Ebbnfow and Ayla,
Can you explain to me what this is and how this works? Thanks

Ebbnflow,
I just checked the website you posted, and I realize this is very complex stuff...At least for my understanding. Is there any simple way for an untrained mind to understand how to use this?

Excel has the best 2d plotter available...

ebbnflow - apologies for not thanking you earlier for posting the link to qudata. Thank you. I have definitely saved it for my "favorite links" for studying more later but as far as drawing a graph, I was unable to get it to do anything but to plot individual points such as TSP I-Fund share prices (Y) vs an integer value corresponding to date (X). Wouldn't connect the points so was just a splatter of points.

Since qudata sells some other products, I wonder if this isn't a very low-scale utility just to draw you in. Anyway, will explore some later. But also in the meantime, I am looking into Excel as ChemEng suggested. Seems like a lot of references to this on the web - i.e. using Excel for plotting.

sponsor, not sure if I can explain a 2d plot. Basically a graph with x values (usually horizontal) vs y values (usually on vertical axis). I had hoped to do some variation of a moving average plot of stock prices but looks like qudata doesn't allow you to compose an equation for y that is an average of numerous values of x.

As far as how I entered the data, I was able to enter the values for the TSP I Fund stock prices from the share price page at: http://www.tsp.gov/rates/share-prices.html. I cut and pasted 30 days into Excel. Couldn't see a way to just cut one column of I-Fund prices.

Then from Excel, I was able to cut just the column of I-Fund prices only (not c-fund, s-fund, etc.).

sponsor, if you need an explantion of a 2d plot, I think there are text books with sections on this. I don't think I could explain this very well here, any more than my statements above.

Hope this helps a little.

Ayla,

If you're interested in plotting moving averages, here's a link to an Excel spreadsheet.-----Rokid

Ayla,
Thank you for your information. I realize that this material is somewhat distant from my usual mindset, professional scope, and work approaches. This seems to be quite suitable for more mathematical oriented types than I am. It doesn't mean that I can't eventually learn this, but it could take some time. Right now I am playing only the I-fund and the G-fund more defensively. However, I will appreciate to hear any conclusions that your work with 2D produces inasmuch as it might affect the trading or investing in the TSP funds. The fact that I don't have a grasp of this subject doesn't mean that I am unable to understand your hypothesis! I am certain that others with similar limitations would also be open to your ideas. Thanks again!
